Narrative:

While working combined radar, MO20 (aircraft X) departed D38 airport VFR and requested IFR clearance to roc. I idented aircraft X and issued vectors for ILS runway 28 approach roc (his request). Approximately 2 mi south of localizer, aircraft X requested a heading to intercept localizer. I issued heading 300 degrees to intercept and cleared aircraft X for the approach. Aircraft X went through the localizer. I then issued a heading of 260 degrees to join and reclred aircraft X for the approach. I observed aircraft X going south through the localizer. I asked the pilot if he had visual on the field and the reply was garbled and weak. Aircraft X transponder began to coast and I believe I lost radio contact at this time. I observed the track of the aircraft continuing towards runway 28. I requested and received clearance to land on runway 28 for aircraft X. I issued the clearance on the frequency and asked the pilot to identify to acknowledge. No identify was observed. On short final, the local controller observed that aircraft X gear was not down and relayed this to me. I issued a go around to aircraft X and received no response. Aircraft X landed gear up. Roc FSDO reported minor damage and classified this is an incident, not an accident.

Title: AN MO20 BEING PROVIDED RADAR VECTORS FOR AN ILS APCH, LANDS GEAR UP, EVEN THOUGH APCH AND TWR CTLRS ATTEMPT TO BRING THE CONDITION TO THE PLT'S ATTN, WITHOUT SUCCESS.

Narrative: WHILE WORKING COMBINED RADAR, MO20 (ACFT X) DEPARTED D38 ARPT VFR AND REQUESTED IFR CLRNC TO ROC. I IDENTED ACFT X AND ISSUED VECTORS FOR ILS RWY 28 APCH ROC (HIS REQUEST). APPROX 2 MI S OF LOC, ACFT X REQUESTED A HDG TO INTERCEPT LOC. I ISSUED HDG 300 DEGS TO INTERCEPT AND CLRED ACFT X FOR THE APCH. ACFT X WENT THROUGH THE LOC. I THEN ISSUED A HDG OF 260 DEGS TO JOIN AND RECLRED ACFT X FOR THE APCH. I OBSERVED ACFT X GOING S THROUGH THE LOC. I ASKED THE PLT IF HE HAD VISUAL ON THE FIELD AND THE REPLY WAS GARBLED AND WEAK. ACFT X XPONDER BEGAN TO COAST AND I BELIEVE I LOST RADIO CONTACT AT THIS TIME. I OBSERVED THE TRACK OF THE ACFT CONTINUING TOWARDS RWY 28. I REQUESTED AND RECEIVED CLRNC TO LAND ON RWY 28 FOR ACFT X. I ISSUED THE CLRNC ON THE FREQ AND ASKED THE PLT TO IDENT TO ACKNOWLEDGE. NO IDENT WAS OBSERVED. ON SHORT FINAL, THE LCL CTLR OBSERVED THAT ACFT X GEAR WAS NOT DOWN AND RELAYED THIS TO ME. I ISSUED A GAR TO ACFT X AND RECEIVED NO RESPONSE. ACFT X LANDED GEAR UP. ROC FSDO RPTED MINOR DAMAGE AND CLASSIFIED THIS IS AN INCIDENT, NOT AN ACCIDENT.
